ChargeMaster Battery Charger - 12 Amp - 3 Bank - 24V Power You Can Rely On Make the most of your batteries with the ChargeMaster, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. The ChargeMaster can charge multiple battery banks simultaneously thanks to its combined functionality. Moreover, all ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (not available on ChargeMaster 24/6). You also have the option of central, local or remote monitoring, configuration and control of your system. The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand. Charging Your Batteries With Every Voltage The Mastervolt ChargeMaster supplies a maximum capacity wherever you are via auto-ranging. Auto-ranging ensures perfect fully automatic operation anywhere in the world, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+ charging technology guarantees fast and complete charging, while the cos phi 1 regulation gets the most out of limited generator capacity.  Sturdy Connections  Metal-on-metal fitting gives a firm connection, and prevents corrosion or overheating of contact surfaces. Charging Multiple Battery Banks  The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two meters of cable for a plug & play solution, while the heavier models have one full output (for example for your service battery) and two outputs of 10 A, ideal for your starter batteries. Features: 3-Step+ charging technology for fast and complete charging. Safe and complete charging due to standard safety features. Memory function prevents overcharging in case of an unstable power supply. Clear control panel. Easy to install.
